Hope everyone had a 'Cool Yule' and
didn't OD on turkey, stuffing, et al.
We're into a New Year and as the long
dark winter nights are certainly here
and the Season's festivities are
behind us we can finally get down to
some serious keypunching trying out
those new programs Santa left under
the tree. If a cassette or two did
not come ricocheting down your
chimney, look up the list of suppliers
printed within and order away. Harvey
T. appears with his usual QL musings.
Those members ordering the QL kit will
be looking for Harvey's past articles
after their kits arrive. New Member
Vince L. drops by with a version of
the Audio Booster, of a few issues
ago, which he says may be safely used
with the 1000 without causing
unnecessary smoke. The Prez has
something to say...so listen up. Ken
A. also passes on the results of his
latest forays into Sinclair Basic. New
Member Joe Jenkins of Amarillo, TX,
sends along a little graphics gem.
The NETWORK Reprints are particularly
bountiful this month with some items
sure to be of interest to all. On the
back page is a form for those members
with Hardware problems they would like
the Hardware Group to address. If you
have a hardware query or are just
uncertain how your machine works, be
sure to take advantage of the
knowledge and brainpower available.
The Hardware Group will be more than
pleased to receive any and all
questions.

EDITOR'S EDITORIAL:
Last meeting Ken asked for a volunteer
to take on the small job of Recording
Secretary. We had a good turnout of
over 30 members but not one member
would volunteer to carry out this
really simple task. Later on in the
meeting a member rose to state that he
was unsure whether he would be
renewing his membership as he was not
sure of ‘what he would be getting for
his money.' It seems that most of the
members of this club have forgotten
what this club is all about. You don't
'get' anything for your membership |
dues. The dues go toward paying the
inevitable costs that arise when 30-40 D
people of mutual interests arrange to
meet to discuss and exchange mutual
points of view. The Group Newsletter
serves as a forum to continue this
exchange as well as allow distant
members to participate. The theory
behind this and any other common
interest club is Contribution, not
Consumption. I, as the Newsletter
Editor, spend many hours contributing
to the viability of this club and I
can say the same for Ken, both as Pres
and as a Newletter Contributor, as
well as the other few members who
contribute. But I'm afraid that this
can't be said of the majority of the
members. Some would say that this is
the way of the world - 10% do while
90% sit on their hands. Well I don't
accept this. You joined this club for
a reason - because you shared a common
passion for a quite uncommon machine.
So start sharing! If you don't do your
share, who will? One day you might
find yourself saying "what ever
happened to that computer club I
thought I belonged to." It probably
ceased due to lack of interest when
you weren't looking. Nuff said?

...the Book Warehouse on Broadway has
a number of TS related books at
incredible prices. This member found
some additions to his library at $1.99
& $2.99 each but was greatly outdone
by Ken A. who picked up a number of QL
related books at 9 CENTS each. He said
he'll be making belated Xmas gifts to
the QL kit buyers. If you can't find
any be sure to ask if any are ‘in the
back'.
...Speaking of books, ZEBRA SYSTEMS
still has lots of stock of the titles
they're offering at $5.00 each,
2@$9.00,or 30$12.00.... A great
bargain.
...be sure to attend this months
meeting. John B. will be demoing all
his WEYMIL wares and will be offering
special pricing to members placing
orders at the meeting.
...the TIMEX REPAIR story has a very
happy ending. As was reported last
time, my 2068 suffered smokeitis and
was sent to the hospital for
treatient. 34 days later a brand new
replacement was left behind the screen
door. The service side of the TIMEX
Computer story isn't over by a Jong
shot. I'm impressed!
...Ex-member and now Robot guru Karl
Brown is offering his renowned 'Build
Your Own Robot Course' one last time.
Call V.V.I. NOW to reserve your spot
because , as we all know, this course
is very popular and when this one is
over - that's itl
..Speaking of ROBOTS, the first
meeting of the new year of the Robot
subgroup, better known as the
VANCOUVER ROBOT CLUB will be at the
usual time and place.(Al Wright's
office, #611 - 470 Granville St. on
Wed. Jan 21/87 at 7:00. If you come
after 7:00 you must press the buzzer
until the maintenance guy comes to
open the door. It would be easier if
you just came before 7:00.) If you
don't have a Robot but want to see
what it's all about feel free to come.
+..the QL kit pricing list has arrived
and members are scurrying off to
various banks with passbook in hand
ready to do massive injury to savings
accounts. Me tool Next issue should
see much to report.
... if you're in the market for some
Software or hardware add-ons don't
forget our own DAVE ROSS. I was over
at his shop the other day and he has
LOTS of good stuff - good prices too.
Give him a call at 874-1756.
-..again, make sure you get to the
next meeting. You could be richer for
it. No, Virginia, not money...a
DOORPRIZE! All attending members will
have a chance at a draw for either
Cruncher 1000 or Cruncher 2068 -- your
choice, if you win. SEE YOU THERE.

The meeting was opened by the Ken, the prez, late as
usual. A request was put to the group for a secretary & an
unearthly silence fell. Out of the unfathomable darkness,
arising from an unplombed depth I found myself growling give
me some paper and I awoke with a pen in my hand. I am δ I
remain Your Humble Scribe. Ken then continued the meeting
with a description of his Zebra sound board containing the
software which censors cusswords. The quality of sound was
described as generally not the equal of the the clubs own
ZXSound.
Rod, the treasurer & editor, described the why of our
dumping the Βοβὶς of Nova Scotia for the more affordable &
sensible New Westminster Credit Union. We presently have
$315.00 in the account. Rod then raised the prospect of
raffling off a QL. After much discussion, a vote carried the
motion with the sole dissenting voice being the one sensible
person present. Rod is working out the details, by default.
Rod then begged for more newsletter articles & got sneaky by
suggesting a monthly “WHAT I DO WITH MY COMPUTER" article by
each member of the group. Everybody thought it was a good
idea, nobody volunteered. Ken wondered whether a fill in the
blanks version would make it easier for the less voluble
among us.
The matter of Killarney membership cards was shelved
indefinitely.
Wilf, the hardware wunderkind, reported that the hardware
group had met Sunday. The new speech board is probably going
to be ready for the next group, with cost in the range of
$7.00 plus or minus $5.@@ depending on whether holes are
drilled or not. There will be an extensive newsletter article
about this board. There were 15 people of the group with an
interest in the project.
The question of whether to drop the borrowers fee to the
ZX81 library was discussed at length. After much discussion,
it was agreed to charge a 31.0 deposit, refundable upon
return of the tape. The question of a 2068 & a QL library was
also raised. Glenn Read mentioned that he had an alignment
tape he had developed for doing Azimuths & Wow and Flutter.
He is going to make this available to the group.
Wilf once again took the floor to describe the Hi-Res &
Extended Basic by Gregory Harder of Denver CO, as well as
his own NOVA multitasking, extension to the ZX video display
which sports a clock, Basic trace, & memory window.
Al Wright, ex-prez & robotics enthusiast, stood to
advertise the last Robotics course by Karl Brown which is
beginning in Jan. at VVI. If you want to take the course, its
now or never.
A disgruntled 2068 member stood to complain that there
was not enough 2868 content to the club. In general, the
point was granted, with the proviso being that its your club;
ie. its up to you! This discussion brought together a group
who were discussing a 2068 library. The organized portion of
the meeting dissolved to general mayhem & Wilf’s NOVA demo.
Listed below, in no particular order, is a list of suppliers
of Software, Hardware, and all manner of other goodies for
the TS family of fine computers. Magazines are highlited
This list is a little dated and a few suppliers
might have ‘folded their tent,etc.,' but almost all should
respond to a request for a catalog. A list of QL suppliers
will be printed next issue.

TIMEX TIPS
by Chuck Dawson
QUESTION: Can you explain the term RLE graphics?
ANSWER: R.L.E. stands for RUN LENGTH ENCODED graphics, which
probably does not tell you a lot. The idea is to take a screen
full of graphic information (usually 256 dots across by 196 dots
high) and turn the information into ASCII characters which can
then be sent via modem to other computers. At the other end, the
ASCII characters are turned back into a visible screen which can
be SAVEd. This is not just a system for use with Timex-Sinclair
computers, but is in wide use with various makes. There are
several public domain programs that encode and decode the screen
information to and from RLE format. Most of the BASIC programs
will ignore the bottom two print lines since the PLOT command
will not work there. Machine code decoders can use the bottom
lines. If you would like to write your oun program, here are the
basics: First, the encoding starts with capital GH to mark the
beginning of the file. Then, the encoding program starts at the
upper left corner of the screen and counts the number of black
dots that appear in a rou, counting to the right. Let/s say
there are three black dots and then a white dot followed by two
more black dots. Since ue are going to use ASCII characters for
our encoding (space thru copyright or CHR$ 32 thru 127), ue are
going to assign space uith the value zero, exclaimation uith the
value one, quotes with the value tuo, and so on down to
copyright with the value of 95. Therefore, our first encoded
character will be # because it has a value of three followed by
! because it is one and finally a ' because it represents tuo.
This counting of black dots and uhite dots continues across the
screen. When the right edge of the screen is reached, drop to
the next line at the far left and keep counting. That is, five
black dots at the end of a line folloued by three black dots at
the beginning of the next line would be encoded as an eight. If
we need a value of more than 95, (like if the whole top line is
black dots), then we encode 95 for black, zero for white, and
95 more for black and so on. The last character in the file is
not ASCII but is a CHR$ 7 (bell). A complicated picture may
easily take much more memory space than a SCREENS but keep in
mind that this system is compatible with other makes of
computers and is easily transmitted via modem systems uhich only
accept ASCII characters. Examples of encoded pictures are
available from many BBSs and are usually named with the suffix
RLE (A picture of Brooke Shields might be named BROOKE.RLE). On
CompuServe you can GO PICS at any ! prompt. This method of
receiving and decoding graphics adds a whole new dimension to
‘computing. I

One of the first things you will want to do once you get
your new QL up & running is get a printer working with it.
Among the ports on the back of the QL are two Serial ports,
but no Parallel port. Most printers use a Centronics style
interface, so that a serial to parallel converter is called
for. There are several of these devices on the QL market as
well as several buffer/converters on the general market,
however a serial to parallel converter oan easily be whipped
up by do-it-yourself'ers. The device that makes this simple
is the UART. The one I have used is the AY3-1915D, but the
16402 could just as easily be used. The only restriction is
that the serial parameters( ie. Stop bits, Word length, Baud
rate ) must be switchable, rather than set by internal
registers.
When I first drew up this design, a year or so ago, I
did not know of the MAX232 chip. I have used that chip in
this version & eliminated the need for a +12/-12 volt charge
Pump, as well as the seperate 1488 & 1489 line driver &
receiver. This chip is available in Vancouver from RAE. I
have included a xerox of the pinout & pin description. You
will notioe in Figure 1 that there are a bunch of Capacitors
hanging off that one chip & these are used precisely to hold
the +12/-12 generated.
Although it might seem that the 74L8373 is superfluous;
in practice I found that once the Printer buffer is full &
the printer sets the BUSY signal to tell the computer to send
no more data, without the 7373, the interface would drop a
character.
I used the 8116 & switches arrangement because I wanted
to be able to set the BAUD rate. The QL is capable of
75, 300, 660, 1200, 2498, 4890, 9666 full duplex & 192008 half
duplex, although I don't think many printers will go 19280
baud. If a person decided they were doing to use only one
baudrate eg. 9600 baud, the orystal ἃ 8118 ( the most
expensive parts ) could be replaced with an RC timing circuit
using a 555 timer or a CMOS 4001 among others.
One of the wonderful little joys of interfacing which
the QL will introduce you to is the difference between DCE &
DTE devices in the R8232 standard. It has become traditional
among QL'ers for some reason lost in the mists of time to use
SER1 for the printer and reserve SER2 for modems ἃ other
goodies. This means that the TxD shown going to the MAX232
chip will be connected to pin 3=RxD of SER1. DTR coming from
the MAX232 will be connected to pin 4=DTR. This topic is
almost described in CONCEPTS under Communications.
Do not omit the ground lines. QL ground from the SER1
port is pin 1. There is also printer ground, & power supply
gorund which all must be connected to the interface ground.

14
The Centronics standard (I have included a xeroxed
description) defines more lines than one actually needs to
use. One can commonly get by with using only STROBE, BUSY, &
the DATA lines. This works fine for Epson printers.
The timing of the 74LS221 multivibrator strobes is set
by the RC network on pins 14 & 15. The width of this pulse is
approximately equal to .69(R*C).
T .69 ( R * C )
.69 ( 2290 * 19E-9)
1.5 E-6
N H Hl
This timing is not oritioal & will work fine as long as
it in this neighbourhood. The strobe must be long enough for
the UART and the printer to see it; while not being so long
that characters are dropped. At 9600 baud there might be 969
characters in a second which means 1/9690, approx 1Κ-3,
between characters. Well within safety range. The minimum
width for the printer is .5E-6 ( 500 nsec.) and for the UART
it is .2E-6 ( 200 nsec.)
Note that on the UART pins 34->39 are all tied high.
This has the effect of setting the Serial parameters expected
to 8 data bits, 2 stop bits, no parity.
HOW IT WORKS
To begin with the printer buffer is empty, so the
printer sets BUSY low to signify it is ready to accept data.
This signal goes to the 74L5221 at 1A enabling other (1B)
input. The signal also goes directly back to the QL through
the MAX232 to tell the QL to go ahead. The QL then sends a
serial byte with start bit & stop bits through the MAX232 to
the UART. The UART catches this serial stream k converts it
back into a parallel form. As soon as the UART has a complete
byte, it sets the DAV (data available) pin which kicks the
74LS221 at 1B and causes it to set Q high enabling the
74189795 buffer’s input latch while simultaneously strobing
the printer with NOT-Q. This signal also clears the UART for
the next oncoming byte. The Output enable of the 74LS373 is
tied low so it is always on. The data from the UART passes
through it virtually instantaneously. After the RC time, the
Q and NOT-Q signals revert to normal.
This process continues until the printer fills up at
which time it asserts the BUSY signal. This has the effect of
taking 1A on the 74L5221 high and preventing any strobes, as
well as telling the QL via DTR to stop. There might at this
point be a byte in transmission. If this is so, the UART will
hold it until BUSY goes low at which point the cycle repeats.
If you run into any problems with this oircuit, Hive me
drop me a line C/O the editor & we'll see if wo can get it
sorted out.

The Vancouver Sun, Wednesday, Dec. 31, 1986
New Year’s Eve is traditionally a time for reflec-
| tion. A time to reflect on what has been. To look
ahead and consider what might become.
Computers are a good topic for reflection because
the industry changes so rapidly.
So, first reflection. It doesn’t take long to become
knowledgeable — in a generic sense — about com-
puters. Although the industry changes rapidly,
there are still only three components to a computer
system — the hardware, software and peripherals.
Once you understand how these
interact with each other, you’re
more than half way there.
Becoming familiar with the
computer industry, both on an in-
ternational and local level,
means becoming familiar with a }
few key players. Ë
oft
column two years ago, software
developers and retail outlets
were springing up continually. A PATTI SCHOM-
number of these companies, MOFFATT
opened and closed their doors
within a year. Those that remain seem to be in it for
the long haul. End-users can now track a company’s
j performance before buying their services.
But while it doesn’t take long to get to know the
industry, it takes forever to understand printer driv-
| ers and figure out how to get a printer to support a
sophisticated word processing program.
e
COMPUTERS
Second reflection. In the last few years, Vancou-
ver has truly become a high-tech centre. Vancou-
ver-based software developers have managed to in-
filtrate both national and international markets
with their products.
And as the industry matures, another industry
builds itself around it. Magazine publishers have
come out with about 30 different computer-related
magazine titles, and writers have written both tech-
New Year's reflections
on a changing industry
When I first began writing this Βασ.
nical and generic books on everything from buying
a computer system to programming with Unix.
All of the major accounting firms now have a
computer consulting arm, and anyone with a back-
ground in computers is now an independent consul-
tant.
Then there are the stock brokers and promoters
regularly bringing high tech firms public. And there
isn't a newspaper that doesn't have a regular fea-
ture about computers.
e
Third reflection. Prices. They never really came
down the way pundits predicted. It's true, you can
now buy a personal computer for less than you could
two years ago, but the speed of computers has in-
creased so much it would be shortsighted not to buy
an XT or AT, which happen to retail for the same
price or more than personal computers did two
years ago.
While your money buys a lot more, you still need a
lot of money to piece together the “minimum” sys-
tem. When all is said and done, your new microcom-
puter workstation will cost $5,000.
This is probably bad news for anyone who has put
off buying a system until the prices came down.
e
Next reflection. Everyone said 1986 was going to
be the year of the laptop computer. It wasn't. While
everyone would like to have one, it's difficult to jus-
tify the cost for the convenience.
Now everyone is saying 1987 will be the year for
desktop publishing. I go on record as saying it won't
happen until the bugs get worked out of the new soft-
ware — which will be 1988.
[
Final reflection. The computer industry joke of
"what's the difference between a used car salesper-
son and a computer salesperson” (answer: the used
car salesperson knows when he's lying), is no longer
true. Now, so does the computer salesperson.

MEMORY CALCULATOR...by Willie Jones
Reprinted from the newsletter of the
Indiana T/S Users Group.
Here is a short utility to use with
the 1000 and the 1500. It will tell
you 5 things:
1) Ram size
2) Program size
3) Display file size
4) Memory used by variables
5) Spare memory
Just tag it onto the end of your
program and call it when needed.
This will show you how your memory
is used up, as well as how much is
left. Access by GOSUB 9200.
